Brandbook Builder

The brand guide free templates can't generate

Every freelance designer eventually needs to hand a client a brand style guide — and every free template gives you the same thing: a page of color swabs, a font name, and not much else. Brandbook Builder closes that gap. It's a single-file app that turns your logo, palette and typography choices into a genuinely client-ready, paginated PDF, and it does the tedious parts for you automatically.

Logo usage, generated automatically

Upload your Primary logo once and Brandbook Builder auto-generates a full set of "incorrect usage" examples — stretched, rotated, recolored, drop-shadowed, on a busy background, crowded with no clear space — without opening Illustrator. Add Icon, Monochrome and Reversed variants, plus configurable clear-space and minimum-size rules for both screen and print.

Color with real print math, and the contrast check most tools skip

• Automatic HEX → RGB → CMYK conversion for every swatch, so the guide works for digital and print production
• Live 60/30/10 usage chart once you assign roles and percentages
• A full WCAG contrast compliance matrix — every palette color checked against every other as text-on-background, with AA / AA Large / AAA pass-fail ratios calculated live, so you catch an inaccessible pairing before the client does

Typography, from a modular scale to a live specimen

Type any Google Font name for heading and body (loaded live), then tune a base size and scale ratio to generate a full H1–H6 + body + caption type scale, previewed in the real typefaces.

Live brand application mockups

A business card, a social media post, a letterhead and an email signature all render live using the client's actual logo, colors and fonts — so the guide shows the brand in use, not just in isolation. Most free style-guide generators stop at swatches and never show this.

Everything else you'd expect from a premium tool

A mood board and imagery/iconography notes section. A voice & tone page with personality-spectrum sliders and do/don't messaging examples. An auto-compiled Do's & Don'ts summary pulled from your logo rules plus any custom rules you add. Four layout themes — Minimal, Bold, Elegant and Tech — while the client's own colors and fonts still drive every page. One-click PDF export via your browser's print dialog, plus a standalone self-contained HTML export for clients who'd rather view the guide in a browser. Unlimited saved client projects with JSON backup/restore, and a built-in Help tab with a full workflow guide and FAQ.
